CRUPPER.

SPECIFICATION forming part of Letters Patent No. 451,561, dated May 5,1891.

Application filed March 26, 1890.

To all whom it may concern.-

Be it known that, I, FREDERICK H. KIEKE- NAPP, of Faribault, in thecounty of Rice and State of Minnesota, have invented certain new anduseful Improvements in Cruppers; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, forming apart of this specification,and to the letters of reference marked thereon.

My invention relates to improvements in cruppers, and particularly tonovel means for connecting the crupper to the billet of thecrupper-strap.

I will first describe my improvements and will then point out theirparticular features of novelty in the clauses of the claim at the end ofthis specification.

Referring to the accompanying drawings, Figure 1 represents aperspective view of a crupper provided with my improvements. Fig. 2 is aperspective view of the elastic plate to which the hook is attached;Fig. 3, a similar view of the socket-plate with which the hook cooperates; Fig. 4, bottom plan view of said socket-plate; Fig. 5, alongitudinal sectional view showing how the hook-plate is capable ofbeing flexed or bent to permit of the ready entrance of the hook intothe socket; Fig. 6, a similar view showing the hook fully entered; Fig.7, a cross-sectional view taken on the line 00 00, Fig. 6. 7

Similar letters of reference in the several figures indicate the sameparts.

The letter A represents the crupper proper; B, the crupper-strap, havingits rear end forked or divided into two billets B E the former of whichis sewed permanently to the crupper, as shown.

Between the parts I) and b, composing the end of the billet B isinserted a thin steel plate C, which bears a hook C, that projectsthrough the lower portion 1), the said plate C being secured in place bystitching the parts I) h together near its edges, as shown.

Serial 110345361. (No model.)

Upon the co-operating end of the crupper is secured by rivets orotherwise a socket-plate D, having a somewhat elongated opening d in itnear one end for admitting the end of the hook C, and grooved orconcaved longitudinally, as shown at d, to adapt it to receive the bodyof the hook C and prevent the same from turning. It will be seen thatthe front edge of the opening is made high and the rear edgedepressed,so that the hook runs readily into place without changing itsangular position. To connect the parts it is only necessary to slightlybend the elastic metal plate C, so as to throw downward and outward theend of the hook C, as shown in Fig. 2, and then thrust said hook intothe opening d of the plate D and draw upon the billet B until the bodyof the hook has fully entered through the said opening d and lies withinthe longitudinal groove D, as shown in Fig. 6, the slight bending orflexure of the plate C, when in the position shown in said Fig. 6,operating to keep the parts tightly locked together.

The means of connecting the billet B to the crupper is very simple andinexpensive, and the joint produced is so neat as to render it difficultfor the ordinary observer to tell to which billet the connecting devicesare applied.

Having thus described my invention, what I claim as new is- Thecombination, with the crupper and the billet of the crupper-strap,- ofthe elastic baseplate held between the parts of the billet and providedwith the projecting hook or tongue and the co-operating plate secured tothe crupper, having the opening and the longitudinal groove forreceiving the hook or tongue of the co-operating plate, substantially asdescribed.
